A In the US, the largest silicone implant on market is 800cc. Saline implants can be overfilled for more volume however, if the volume exceeds the upper end of the manufacturer’s recommendation, the implant warranty is voided. So, you have no protection in the event of early rupture.
In the past, occasionally implants were stacked on top of one another often times with bizarre looking results and hefty costs for revision surgery.
Long term, there is only so much our skin can take. Heavy implants stretch our skin prematurely and often make us look wider and as if we’ve gained weight.
Sometimes fat can be grafted from one area of the body to another to help boost volume in addition to an implant but this type of volume would not get you to your goal cc’s.
I’d advise seeing more than one plastic surgeon who can advise you regarding implant size based on your tissue and frame. We want you to be happy but also age well with your implants. Really talk through the potential pitfalls of large implants. You may change your mind. Best of luck to you!!
